30. You don't need women now.

There are test tubes and incubators and surrogates (whom you need have nothing to do with after they've incubated your kid). As far as the pleasure aspect of the whole mess - well you can "handle" that yourself too.

But you have to clean your own toilet, do your own laundry and cooking and vacuum your own floors, change the diapers and clean up the puke and run the little varmits all over the place until they're old enough to drive and take time off work to do it all yourself while saving for their college and your own retirement. That's what women do.
